Duodenum has characteristic Brunner’s glands which secrete two hormones called :

Options

A. Kinase, estrogen
B. Secretin, cholecystokinin
C. Prolactin, parathormone
D. Estradian, progesterone

Answer

### Step-by-Step Solution:

1. **Identify the Structure**: The question refers to the Brunner's glands, which are located in the duodenum, the first part of the small intestine.

2. **Function of Brunner's Glands**: These glands are known for their role in secreting alkaline mucus that helps to neutralize gastric acid and provides an optimal pH for the function of intestinal enzymes.

3. **Hormones Secreted**: The Brunner's glands specifically secrete two important hormones:
- **Secretin**: This hormone stimulates the pancreas to release bicarbonate, which helps to neutralize stomach acid in the duodenum.
- **Cholecystokinin (CCK)**: This hormone stimulates the gallbladder to release bile and the pancreas to release digestive enzymes.

4. **Conclusion**: Therefore, the two hormones secreted by Brunner's glands are Secretin and Cholecystokinin (CCK).

### Final Answer:
The two hormones secreted by the Brunner's glands in the duodenum are **Secretin** and **Cholecystokinin (CCK)**.
